The equation to find the volume of a cylinder is V=

×r²×h. To find r you just divide the diameter which is 10 by 2 so r is 5. Just plug everything in and solve, V=

×5²×243.84. You should get V≈19,151.15
Hello! :)

Use the exponential rule:

Use this property in this scenario:

Simplify:

The possibility that at least 5 are correct is:
(1/5)^5=1/3125
